Fig.7
(~0.1Mb) An image of the O VI 1032 Å line intensity and line width
(assuming a single Gaussian profile) as a function of height and position
above the limb obtained during the raster scan on May 22, 1996. The most
notable feature is the striking anti-correlation between line intensity and
line width near central meridian.
